CORNER CONSTRUCTION FOR RECTANGULAR FRAMES.

Specification of Letters Patent.

PatentedApr. 2, 1918.

Application filed January 20, 1917. Serial No. 143,438.

To all whom it may concern:

Be it known that I, WILLIAM B. ANDER- soN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Corner Constructions for Rectangular Frames, of which the following is a specification.

My invention relates to improvements in corner constructions for rectangular frames and has especial reference to frames, such as those used in wire fabric bed bottoms and bedstead structures.

One of the objects of my invention is to.

improve the appearance and decrease the cost of production of rectangular frames where one or more members thereof is composed of angle-irons, or bars.

Other and further objects of my invention will become readily apparent, to persons skilled in the art, from a consideration of the following description when taken in y conjunction with the drawings, wherein Figure 1 is a plan view of a portion of a rectangular frame shown in connection with a bed bottom.

Fig. 2 is a side elevation, part of which is shown in section, taken on line 2-2 of Fig. 1. I

.Fig. 3 is a bottom view, part of which is in section taken on line 3-3 of Fig. 2.

I Fig. 4 is an isometric perspective of an end of one frame member.

In all the views the same reference characters are employed to indicate similar parts.

In the specific illustration 5 is a portion of the side rail of a bed-bottom and 6 is a portion of the end rail, located at a different elevation, and connected at the corners by. a bracket including inclined tubes 8 and 9. A bracket member 10 provides a socket 11 for the tube 8, and a socket 12 for the tube 9, and another socket 13 for the tubular side rail 5. Secured to the end rail 6 is another member 14: of the corner bracket that provides a socket for the upper end of the tube 8. The tube 9 may be connected directly to the vertical leg 15 of the end rail 6, as shown at 16. The end rail 6 is of angle-iron formation, providing a vertical leg 15 and a horizontal leg 16. To produce the round ornamental corners I separate the vertical leg 15 from the horizontal leg 17 by a slot 18. I then shorten the horizontal leg and round the end portion 19, and curve the vertical leg 15 around the rounded portion, as at 20. I provide a plate 21 which is riveted or otherwise secured to the horizontal leg 17, as at 22, and which has a downturned flange 23 to overlie the upper edge 20 of the vertical leg 15 to retain it in the position in which it has been bent and to provide a finish. The plate 21 may have an extending portion 24 to which to attach another member of a rectangular frame or the border margin 25 of a spring bed bottom. The wire fabric 26 may be conected to the end frame member 6 through helical springs 27, and at its longitudinal edge may be connected to the border 25, as at 28, as usual in such structures.

Having described my invention, what I claim is A frame member comprising an angle-bar having angularly disposed legs separated from each other at one end by a longitudinal slot, one leg being shortened and rounded; the other leg bent around the rounded end of the shortened leg, and a plate overlying said slot having a rounded angularly disposed flange extending over the vertical edge of the bent leg to hold the latter in place and having an angularly extended portion to which to attach a border member of a spring bed bottom. 1

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
